To all whom it may con-cam:

Be it known that l, Enrsn Messrs .1?? re siding at San Diego, in the county oi San Diego and. State of Celicl ornnr have invented certain new and useful improvements in Roller-Bearings of which the following is a specification.

My invention relates to certain useful. improvements in roller bearings oi the sntiirietionelly spaced circular series type, and it primarily has for its object to provide bearing as neerly frictionless as possible, while at t e same time producing a bearing of e simple end efi'ective construction which can be easily and cheaply menu- :t'ectured and which will readily serve its intended purposes.

Again my invention has for its ob ect to provide at bearing in which the parts are interchangeable and may be replaced when conditions require.

Genericelly my invention embodies a bearing sleeve removsbly held on the axle between two roller reteiners, double cone bearing rollers serially arranged around the sleeve with their asses parallel to that oi the sleeve. is bearing roller sleeve surrounding the rollers and adapted to loo held to the rollers to turn therewith, together vitl'i spacing cone rollers ha ing shefis tcrrni mating in groovedrollers that hell in runways formed between. roller and. e cooperating held tliereoz'i.

My invention. elsoincludes these specific constrnctionsr combinations and arrangernents or pelts which will be liercineifter fully described specifically pointed oit the eppended claiins, and illustreted in the accompanying drawings; in which:

Figure l, is 2, central section of my invention taken on the line 1-l of Fig, 2. Fig. 2, is a cross section on the line 2 2 of Fig. 1. 3, is e cross section on the line 8 3 of Fig. 1. Fig. i, is a detail perspective View of the she-ft sleeve: .s ig. 5, is at similar View of the roller reteineie Jig, 6, is detail perspective view of t 1g that cooperates with the retainer. 1g. spective View or. one of the bearing rollers. Fig, 8, iss similar View or one of the spec lng rollers. I

Herein to the sccornpenylng drawings in which like ls tors and numerals of reference indlcate like parts 111 all of the figures, i designates the shaft which is pro- 7, is 3 nee-- vided W" the spindle l and the threaded cap receiving portion 1*. v

2 represents the-shaft sleeve which is rer'lovaoiy held on the shaft and is 01" double cone shape With the apex portions of the cone surfaces adjacent to one another.-

he shaft 1, whereit joins its spindle portion 1 is formed. with a shoulder l to form n stop for the roller retainer 3, which e nub portion 3 spertured to fit on the spindle l and is provided with a peripheral portion 3 Insving an internal V-shaped track 3 to act in connection. with the track at" of the ring l to retain the grooved rollers 5 of the spacing rollers 5 between the same, and form a runway therefor. flhe ring 4: is epcrtured to fit on the sleeve portion 8 of the retainer 8 and aline with the track 3 thereof. A roller retainer 3 and a ring 4 are mounted at each end of the sleeve 2.

Th2 spacing rollers 5 are of similar form in side elevation to the sleeve 2, namely, are formed of double truncated cone sections with their portions of least diameter abutting one another and the spacing rollers 5 are formed with shafts 5 that terminate in the rollers (5 represents the bearing rollers which are formed or? double truncated conical sections with their portions of greatest diameter abutting one another as clearly indicated in Fg l of the drawings. The bearing rollers 6 lie between the sleeve 2- on the spindle 1 end the slee es '7 which form the hub lining, the sleeves '7 being formed with counter sunk portions 7 forming shoulders 7 to revs the roller retainers 3, as clearly shown in 1. of the drawings, and thus act as dustouards to prevent dust and dirt entering into the bearings. Each hub sleeve 7 is of like form and has its roller engaging surface formed of a truncated cone shape with its portion of greatest diameter at the cent-rel or inner end and its portion of least diameter adjacentto the countersunk per tion 7 thereof.

In assembling the parts-the member 3 is first slid on the shafts and the rollers 5 at one end of the shafts 5 are placed with their grooves in the member 3 and one member 7 is placed into position, after which the rollers 6 are placed into position. The other member 3 with the member f thereon and the rollers 5 which are loose or detachable from the shafts 5 are then slid onto the end of the spindle with the other member 7 thus completing the assembling of the parts.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.

The hub sleeves 7 may be made a slight 1 distance apart so that in case of wear on sleeve havin the bearings the same may be taken up by screwing the two sections of the sleeves 7 toward one another.

What I claim is: 1. In a roller bearing, a shaft sleeve having a peripheral bearing surface, a hub an internal earing surface to cooperate with that of the shaft Sleeve, interposed bearing rollers between the bearing surfaces of the shaft and hub sleeves, spacing rollers between said bearing sleeves, said spacing rollers having shafts, and grooved wheels mounted on said shafts on the ends .hub sleeve having countersunk portions to receive said retainers and form therewith a closure for the bearing rollers.

2. In, a roller bearing, the combination with a spindle, of roller retainers removably mounted on said spindle and spaced apart, ashaft sleeve mounted on said spindle between said roller retainers, said shaft sleeve having a double cone peripheral bearing surface, a hub sleeve having an internal bearing surface, combined with a series of double cone bearing rollersinterposed between the bear ing surfaces of the hub and shaft sleeves and spacing rollers carried by said roller retainers.

3. In a roller bearing, the combination with a spindle, of roller retainers removably mounted on said spindle and spaced apart, a shaft sleeve mounted on said spindle bet-ween said roller retainers, said shaft sleeve having a double cone peripheral bearing surface, a hub sleeve having an internal bearing surface, a series of double cone bearing rollers interposed between the bearing surfaces of the hub and shaft sleeves, said hub sleeves having countersunk portions to receive said roller retainers to form a closure for the bearings, said roller retainers having internal trackways and spacing rollers interposed between adjacent bearing rollers and having shafts terminating in grooved sleeves having countersunk portions to re ceive said roller retainers to form a closure for the bearings, said roller retainers havmg internal trackways, spacing rollers 1nterposed between adjacent bearingrollers and having shafts terminating in grooved wheels to cooperate with said trackways of said roller retainers, and rings carried by said roller retainers and provided with peripheral tracks to'cooperate with the roller retainer track.

5. In a roller bearing, a pair of spaced roller retainers having hub ortions to receive a shaft spindle, a sha sleeve. interposed between said roller retainers and provided with a peripheral doubly coned bearing surface, double cone shaped bearing rollers serially arranged around said sleeve to cooperate therewith, a pair of hub sleeves surrounding said bearing rollers, said hub sleeves having countersunk ortions to receive said roller retainers an form closures therewith, double cone sha ed spacing roll: ers interposed between sai bearing'rollers, having means mounted within the roller retainers to retain and guide the spacing V rollers.

6, In a roller" bearing, a pair of spaced roller retainers, having hub ortions to receive a shaft spindle, a sha sleeve interposed between said roller retainers and provided with a peripheral doubly coned bearmgsurface, double cone sha ed bearing rollers serially arranged aroun said sleeve to cotiperate therewith, a pair of hub sleeves surrounding said bearing rollers, said hub sleeves having countersunk portions to receive said roller retainers and form closures therewith, double cone shaped spacing rollers interposed between said bearing rollers, said spacing rollers having means mounted within the roller retainers to retain andguide the rollers, said'last named means comprising shafts projecting from said retaming rollers, grooved wheels mounted on the ends of said shafts, said roller retainers having an internal track to cooperate with saidlast named wheels.

7. In 'a roller bearing, a pair of spaced roller retainers having hub ortions to receive a shaft spindle, a shaft sleeve interposed between said roller retainers and provided with a peripheral doubly coned bearing'surfaoe, double cone shaped bearing rollers serially arranged around said sleeve to cooperate therewithla pair of hub sleeves surrounding said bearing rollers, said hub sleeves havin countersunk portions to receive said r01 er retainers and form closures therewith, double cone shaped spacing rollers interposed between said bearing rollers, said spacing rollers having means mounted within the. roller retainers for retaining the spacing rollers, said last named means comprising shafts projecting from said retaining an internal track to cooperate with said last named wheels, together with a ring carried by said roller retainers and provided with a peripheral track to cooperate with the first mentioned track to form a runway for said last mentioned rollers.
